I was trying to flash a TWRP backup but when I booted I came to a lock screen that I do not know the pattern for and also there are random symbols such as % in the text on screen. When I try to boot recovery, with buttons, it will just reboot. Is there any other solution to try and factory reset? I cannot use adb as when I plug in phone it reads as a media device. Also a box keeps appearing saying "%1$s is not responding."
